Agreed, If your buying it go ahead and get a version of Vista 64. I would say as new as Vista is, it has less driver problems than XP 64 still to this day.
I'm not buying it, I downloaded it from Microsoft, along with a 120 day free-pass.. I was thinking about trying it as I have all of the XP drivers for my board.
I use, and like, Vista Basic.. I'm not looking to switch, just looking for something to mess around with
